Process for the preparation of urethane resins and urethane resin compositions

ABSTRACT

A process for the preparation of urethane resins, which comprises the steps of: preparing a product (A) having a hydrolysable group directly bonded to 1–10 silicon atoms and having less than two secondary amino groups in one molecule; preparing a product (B) having a terminal isocyanate group in an amount 4% or less by weight of the product (B); and reacting the product (A) with the product (B) in proportions of at least 0.5 equivalent of the product (A) per free NCO group of the product (B). The process readily gives urethane resins, which exhibit excellent storage stability and are enhanced in the degrees of freedom of the physical properties of the products of curing.

FIELD OF THE INVENTION

The present invention relates to a process for the preparation of urethane resins and urethane resin compositions. More particularly, the present invention relates to a process for the preparation of urethane resins endowed with fast curing property and non-foaming property by modification of the terminal of an isocyanate resin and urethane resin compositions.

DESCRIPTION OF THE RELATED ART

An isocyanate group terminal moisture-curing type resin has excellent adhesion against wide range of materials to be adhered, however, when the isocyanate group content is low, there are defects that long period of time is necessary for curing though it forms an excellent elastomer, and storage stability is poor depending on the kind of the isocyanate compound, and the like. There are trials for reducing curing time that a prepolymer is produced using partially an amine polyol, various catalysts are used, and the like, however, effects thereof are not sufficient. Japanese Patent Application Publication (JP-B) No.2594024 shows a method for producing a urethane resin in which a urethane prepolymer is terminally-capped with an arylaminosilane, however, there are problems that the production of the arylaminosilane is expensive, and the like.

Further Japanese Patent Application Laid-Open (JP-A) No. 8-283367 describes a wet-curing resin composition obtained by compounding a polymerization inhibitor of a free mercapto group into a urethane prepolymer system containing an alkoxysilyl group and a free mercapto group. This composition aims for improvement of curing inhibition due to the reaction of the urethane prepolymer with the mercaptosilane, however, the curing speed can not be evaluated sufficient. Moreover, if a urethane prepolymer is wished to be modified only with a mercaptosilane, curing inhibition is caused when the amount of the mercaptosilane is over equivalent to the amount of the isocyanate (in the case of use of a usual tin catalyst), and thickening can not be avoided due to the remaining isocyanate and control of the reaction is extremely difficult when the amount of the mercaptosilane is too low.

Recently, in adhesion of different materials having different expansion coefficients, elastic resins are noticed and use range thereof is enlarged since it has been found that such resins have various excellent properties. The elastic resins naturally manifest value as a base for sealing materials. Further, there exists background that one-liquid adhesives containing no solvent should be increasingly required from now on in view of environmental problems, workability and the like. For producing a urethane elastic adhesive which is relatively cheap, the content of an isocyanate group has to be restricted to at most 5% by weight or less, and particularly when sufficient elongation is expected, the content has to be restricted to 4.0% by weight or less. In this case, however, the following problems occur. (1) Storage stability deteriorates depending on the kind of isocyanate compounds, and particularly in the case of an aromatic compound, it significantly deteriorates. (2) Curing is delayed significantly irrespective of the kind of isocyanate compounds, and particularly in the case of an aromatic compound, the delay is remarkable. (3) Foaming, and reduction in physical properties and adhesion due to low content of an isocyanate group may occur. For solving these problems, various means as described in the conventional technologies have been tried, however, complete solution has not been accomplished yet.

Though it is believed that reactivity can be solved by introducing a reactive group such as a hydrolyzable group-containing silyl group, hydrolyzable group-containing titanate group, epoxy group, (meta)acryloyl group, vinyl group, ethynylene group and the like into the terminal of a molecule, the problem is means thereof. When a primary amino group-containing alkoxysilane is solely used for modification, serucing of safety is extremely difficult. Further, isocyanate silane compounds for which application of aryl-modification and other modification methods as described in the conventional technologies are easily thought out include problems such as high cost and the like.

Namely, the present invention has been accomplished for solving the above-described conventional problems, and an object thereof is to provide a process for the preparation of urethane resins which can easily produce urethane resins having features that modification of the terminal of a molecule is easy, curing speed is fast, degree of freedom of physical properties of a cured material is extremely high.

For attaining the above-described object, the present inventors have been intensively studied and as a result, have found a modification method by which modification of the terminal of a molecule can be easily conducted even in a urethane prepolymer having low isocyanate group content, and which provides excellent curing property and storage stability, and found that there exists a system in which physical properties of a cured material and curing time can be freely modified by controlling the amount and modification method thereof in modifying a terminal isocyanate group or isocyanate monomer in a urethane prepolymer with the modified compounds, further have found that cost reduction per unit weight is possible even with the above-described arylaminosilane and isocyanatesilane by modification using a second component and that a mercapto group-containing silane coupling agent can be used by contriving use method and modification method thereof, completing the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION

The preparation process (1) of the present invention comprises the following three steps.

In the first step, the above-described compound (a) and/or a zircoaluminate compound is reacted with the above-described compound (b) at a temperature from −20° C. to 150° C. for 1 to 1000 hours to produce a zincoaluminate reaction product or a compound (product A) having less than 2, preferably from 0.1 to 1.5 secondary amino groups (—NH—) or hydroxy groups (—OH) in one molecule and having 1 to 10 above-described hydrolyzable groups directly bonded to a silicon or titanium atom. The reaction may be effected in the presence of a medium such as an organic solvent and the like, and can be effected for over 1000 hours without any problem. The compound (a), compound (b) or zircoaluminate compound may be used not only alone but also in combination of two or more. Regarding use ratio of the compound (a) and/or zircoaluminate compound and the compound (b), the amount of the compound (b) is usually α

(0.1 to 9) mol (α≦1) or (α−1)

(0.1 to 9) mol (α>1) per one mol of the compound (a) and/or zircoaluminate compound when the number of the organic group (I) in the compound (a) or zircoaluminate compound is represented by α, however, this amount is appropriately controlled depending on the reaction conditions of the product A and product B in the third step described below, odor produced, and the like. The compound (b) may also be used in excess amount to be allowed to remain in the final cured material and to act as a plasticizer, however, such large amount to cause bleeding is not preferable. However, even if the compound (b) is used in excess amount, when the compound (b) is a compound which is polymerized by photo-curing initiator and the like such as α, β-unsaturated carbonyl compound, α, β-unsaturated nitrile compound and the like, there is no problem if it is used together with a photo-curing initiator and is cured.

Then, in the second step, one or more compounds or products selected from the above-described compound (c), the-above-described compound (c-1) and the above-described product C are reacted with the above-described compound (d) and/or the above-described compound (d-1) to produce a (thio)urethane prepolymer (product B) containing terminal isocyanate and/or isothiocyanate groups in an amount of 4% by weight or below. In this procedure, it is necessary that the content of the isocyanate and/or isothiocyanate groups in the product B is 4% by weight or below, and when it is over 4% by weight, the object of the present invention is not attained. The reaction of the compound (c), the above-described compound (c-1) or the product C with the compound (d) and/or the compound (d-1) may advantageously follow methods usually conducted in preparing urethaneprepolymers.

Further, in the third step, the above-described product A is reacted with the above-described product B in proportions of 0.5 equivalent or more, preferably from 0.5 to 10 equivalent of the product A per free isocyanate and/or isothiocyanate group of the product B to produce a urethane resin (product X). More particularly, the number of the free isocyanate and/or isothiocyanate group is represented by β and the number of the active hydrogen reactive with the isocyanate or isothiochanate group in the above-described product A is represented by γ, the amount of the above-described product A shall be β/γ

(1 to 10) equivalent and the free isocyanate and/or isothiocyanate group shall all disappear. The reaction of the product A with the product B is desirably conducted in the presence or absence of a compound having catalytic action, preferably in the atmosphere of an inert gas such as a nitrogen gas and the like at a temperature from room temperature to 110° C. for 1 to 1000 hours. Alternatively, this reaction can also be conducted in the presence of a medium such as an organic solvent and the like.

As the above-described compound having catalytic action, an organotin catalyst, metal complex, basic substance, organic phosphoric acid compound and the like can be used, and examples of the organotin catalyst include dibutyltin dilaurate, dibutyltin diacetate, dibutyltin oxide, stannous octoate, dibutyltin phthalate, dibutyltin methoxide, dioctyltin dimaleate, dibutyltin diacetylacetate, dibutyltin diversatate and the like, examples of the metal complex include titanate compounds such as tetrabutyl titanate, tetraisopropyl titanate, triethanolamine titanate, tetrakis(2-ethylhexyloxy)titanium, tetrastearyloxytitanium, diisopropoxy. bis(acetylacetonato)titanium, di-n-butoxy. bis(triethanolaminato)titanium, titanium. isopropoxyoctylene glycolate and the like, titanium carboxylates such as titanium stearate and the like, metal carboxylates such as lead naphthenate, nickel naphthenate, cobalt octyalte, lead octylate, cobalt naphthenate and the like, and metal acetyl acetonate complexes such as aluminum acetyl acetonate complex, vanadium acetyl acetonate complex and the like, examples of the basic substance include aminosilanes such as γ-aminopropyltrimethoxysilane and the like, quaternary ammonium salts such as tetramethylammonium chloride, benzalconium chloride and the like, and straight-chain or cyclic tertiary and quaternary ammonium salts containing a plurality of nitrogen atoms such as DABCO (registered trade mark) series, DABCO BL series and the like manufactured by Sankyo Air Products, examples of the organic phosphoric acid compound include monomethylphosphoric acid, di-n-butylphosphoric acid, triphenyl phosphate and the like.

In this reaction, the free isocyanate and isothiocyanate groups in the product B all react with the product A and the isocyanate group and the isothiocyanate group completely disappear. The amount used of the compound A is practically satisfactory when it is within the above-described range, however, even if the compound A is used in an amount over the range, there is almost no problem in ability thereof except slightly delayed curing. However, use in an amount over the above-described range is not preferably since cost increases. The above-described catalyst can also be utilized as a curing catalyst for the reaction product.

The product C is produced by reacting the compound (e) with the compound (f) in proportions of δ

(0.1 to 3) mol of the compound (f) per mol of the compound (e) when the total number of the group (II) in the compound (e) is represented by δ, at a temperature from about −20% to 150° C. for 0.1 to 1000 hours. There is naturally no problem if a plurality of an amino group, acryloyl group, epoxy group, mercapto group and the like are contained in the same molecule in the compound (e) used in the above-described reaction. The above-described reaction may also be conducted in the presence of a medium such as an organic solvent and the like, and there occurs no problem if the reaction is conducted for over 1000 hours. In the above-described reaction, a catalyst such as an organotin compound, amine compound, organometal compound and the like may be added without any problem. The compound (e) and the compound (f) may be used not only alone but also in combinaiotn of two or more. Use proportion of the compound (e) to the compound (f) is appropriately controlled depending on reaction conditions, cost and safety.

The product X can be produced by the following preparation process (2) instead of the above-described preparation process (1). In the preparation process (2), the above-described product A in an amount of less than β/γ equivalent per free isocyanate and/or isothiocyanate group in the above-described product B, a compound (g) which has an organic group (III) carrying a primary amino, secondary amino, hydroxy and/or mercapto group in the group and has 1 to 10 hydrolyzable groups selected from alkoxy, acetoxy and oxime groups directly bonded to a silicon or titanium atom, a zircoaluminate compound or a compound (h) having an organic group reactive with an isocyanate or isothiocyanate group (these are referred to as compound Y) and the above-described compound B, are reacted in proportions of β/ε

(1 to 10) equivalent of the total amount of the above-described product A and compound Y per free isocyanate group in the above-described product B if the number of active hydrogen atoms reactive with an isocyanate or isothiocyanate group in the above-described product A and compound Y is ε.

The reaction conditions of the product A, compound Y and the product B may advantageously follow those in the case of the reaction of the product A with the product B in the third step in the preparation process (1), however, the reaction order thereof is important. Namely, the product A is reacted with the product B previously, then, the compound Y is reacted with the product B, or the product A and the compound Y are simultaneously reacted with the product B.

Into a reaction vessel were charged polyols and polyisocyanate compounds shown in Table 5 in proportions shown in the table, and they were reacted for 3 hours at 90° C. with stirring in nitrogen atmosphere to obtain products B. In Comparative Example 1, KBM 903 was charged, and the reaction was stopped immediately.

Comparative Examples 4, 5

Into a reaction vessel were charged polyols and polyisocyanate compounds shown in Table 5 in proportions shown in the table, and they were reacted for 6 hours at 90° C. with stirring in nitrogen atmosphere to obtain products B.

The products were kept for 1 week and 2 weeks at 40° C., then, viscosity and isocyanate contents were measured and results thereof are shown in the tables.

Comparative Example 11

A product was obtained in the same manner as in Comparative Example 2 except that 10 parts by weight of KBM 803 was further used in Comparative Example 2,

As shown in tables, any of the products X obtained in the examples exhibited excellent storage stability, and could provide a resin composition having excellent curing property without foaming by addition of a tin catalyst (No. 918).

As shown in Comparative Example 1, a product having excellent stability can not be obtained by addition of only a silicon compound containing a primary amine. Further, as shown in Comparative Examples 2 to 5, if reaction with the product Σ is not conducted, a product having excellent storage stability can not be obtained or curing requires 2 days or more even if storage stability is excellent.

Further, as shown in Comparative Examples 6 to 10, a product having excellent storage stability can not be obtained if the remaining isocyanate in a prepolymer is not substituted by the product Σ in equivalent or more.

Then, a catalyst (No. 918; manufactured by Sankyo Yuki Gosei K.K.), calcium carbonate heavy of which water content had been controlled to 1000 ppm or less (trade name: NS 2300, manufactured by Nitto Hunka Kogyo K.K.) and partial amino silane (trade name: KBM 603, manufactured by Shin-Etsu Chemical Co., Ltd.) were compounded into the products obtained in Examples 4, 5, 6, 13, 21 or Comparative Example 11 in proportions shown in Table 7.

These compositions were sufficiently mixed by a planetary mixer under reduced pressure, then, time before surface tension was measured. Sheets having a size of 1.5 mm were made from the compositions and left for 7 days at a temperature of 23° C. and a relative humidity of 50%, and storage elasticity coefficients and loss elasticity coefficients were measured at 20° C. and the results are shown in Table 7.

Dynamic viscoelasticity of the cured material was measured using RDS-11 manufactured by Rheometric Far East K.K. at a frequency of 1 Hz with temperature range of −100° C. to 100° C. at a temperature rising speed of 5° C./min. Spectrums of dynamic viscoelasticity of cured materials of the products obtained in Example 5 and Example 21 are shown in FIG. 1 and FIG. 2 respectively. Peak tops of tan δ are represented by tan δ (lower temperature side) and tan δ 2 (higher temperature side), and temperatures there of are also shown in Table 7 together.

From these results, it is known that resin property is influenced by the difference between a hard monomer and a soft monomer. Further, it is known that curing time significantly differs depending on difference in modification method of the product Σ. Particularly, the products obtained in Examples 4, 5, 6 and 21 show a tension time of 10 minutes or shorter, therefore, it is known that a resin having higher curing speed can be obtained. Further, it is also known that the product obtained by the modification method in Example 13 can delay curing time. The product obtained by the modification method using only a mercaptosilane in Comparative Example 11 is not cured even after 1 week. The products obtained in Example 5 and 21 exhibit storage elasticity coefficients of 1×10⁴ and 2×10³, namely, significantly different resin property. Further, it is also known that glass transition temperature varies significantly by the difference of modification method (product Σ) even if the main chain is identical, peak of when tan δ is regarded glass transition temperature. Therefore, it is shown that formulation can be selected in view of both urethane prepolymer (product B) and modified material (product Σ) according to intended abilities.
